Software engineer

Nattawut K.

I build web apps, APIs and the servers behind them.

A developer who works across the whole stack, from the web page to the server, and likes building small software that fixes everyday annoyances.

  • Web applications
  • Backend APIs
  • Bookkeeping apps
  • CI/CD pipelines
  • Cloud infrastructure
  • macOS apps
  • Next.js
  • TypeScript

02 / About

From web page to server

Full-stack developer.

I work across the whole system, from the pages people see to the APIs and servers behind them. Most of my work is web apps that people use every day.

Beyond the code, I look after CI/CD and servers too, so deploys stay simple and systems keep running.

When something gets in my way at work, I tend to write a small tool to fix it, like Cmdly.
